In the whole process, I was taught that although we each had our own job to do in a show, all of us need to work together to make the show great.
四、Dear students，
Following Safety Education Day, it's our safety education time this week.Here I'd like to take the chance to tell you some safety rules.
Firstly, you should pay attention to traffic safety.On the way to and from school, follow the traffic rules strictly.If you walk, you should walk on the zebra crossing when crossing the roads.If you ride, remember you can't ride electric bicycles on the roads if you are under 16 years old.If you take the bus, never put your heads or hands out of the window.
Secondly, school safety is of the same importance.To avoid hurting others, you mustn't bring dangerous toys, knives or sticks to school.During break time, you are not allowed to run or play in the classroom or in the hallway in order not to knock into the desks or walls.Also, you have to try to be careful when you do all kinds of work in school, such as sweeping the floor, moving the table or cleaning the windows.
I hope all of you can keep in mind that safety always comes first, and take active action to improve your ability to protect yourselves.
